Which system of equations has the same solution as the system below? 3x+3y=8 2x-y=5 a. 3x+3y=8 4x-2y=5 b. 3x+3y=8 4x-2y=10 c. x+y=8 2x-y=5 d. 9s+9y=22 18x+9y=45

The correct option is B. 3x + 3y = 8 and 4x - 2y = 10

Step-by-step explanation:

The given system of equation is :

3x + 3y = 8

2x - y = 5

On solving both the equations, We get

Now, The system of equation in B is :

3x + 3y = 8

4x - 2y = 10 ⇒ 2x - y = 5

So, This system is equal to the given system of equation

So, The solution to this system will also be the same to the given system of equations

Therefore, The correct option is B. 3x + 3y = 8 and 4x - 2y = 10

answer: a video game has three difficulty levels: easy, medium, and expert. the game's scoring works in such a way that a player has to score a fixed number of points to advance to the next level, and then the scoring starts over. the total score needed to clear all three difficulty levels is 7,500. two times the number of points needed to clear the easy level is 500 more than the number of points needed to clear the medium level. twice the number of points needed to clear the medium difficulty level is 1,500 more than the number of points needed to clear the expert level. if x, y, and z represent the easy, medium, and expert levels, respectively, and a is the coefficient matrix of the system of equations modeling this situation, identify the inverse matrix, a-1, and the solution matrix, x, of the system of equations.
